But Calvin Harris has changed our minds, confirming that informing your missus that she is single by TWEET is a much colder method.

In possibly the most awkward celeb break-up since the time Matt Damon dumped Minnie Driver during an Oprah interview, Rita Ora reportedly discovered her relationship was over via Twitter.

In fact, the RIP singer apparently found out she was single at the same time as Calvin's 4.28 million followers.

The year-long romance between Rita and her Scottish DJ fella had been rocky for several weeks, but the 23-year-old singer believed that they could work through their issues.

However, Calvin had different ideas, and tweeted: "To address speculation - myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best."

According to reports, this tweet was a shock to Rita, who was completely blindsided by the split, which was allegedly caused by the Hot Right Now songstress spending too much time with Justin Bieber and his rapper mate Khalil.

A source told The Sun: "It was Calvin’s decision to end the relationship. They had been arguing for months and had grown apart.

"She was constantly posting snaps of her with other groups of friends and her trip to Mexico and photos of her with Khalil were the final straw. Calvin likes more privacy than Rita and he hated the extra attention that came with being her boyfriend.

"Rita was left embarrassed when he tweeted that it was all over. She didn’t think he was going to make the announcement, so she was shocked."

Calvin was still referring to Rita as his "missus" at the start of May, telling the Daily Star: "We see each other like four days every two weeks, so it’s like an issue when she’s around. We’d probably get sick of each other if we had a whole month (together)."

Meanwhile, Rita had been gushing about the Acceptable In The 80s hitmaker constantly, saying back in April that she was "obsessed" with him and that seeing him in the studio made her "seriously hot".

Let's just hope that the exes don't bump into each other during festival season – or get asked to perform their collaboration I Will Never Let You Down.
